thanks for the information. It is interesting that fare buckets are used. considering when you purchase say a flexi saver or red e-deal that allows upgrades or a super saver and that there can be many classes in those buckets, how do they work which class is above another. Also to note that it is impossible to purchase a Y class economy ticket on line, even if you select fully flexible for int'l flight it will never assign a full Y class. But on domestic they class flexi saver and fully flexible as full Y for SC earn. a bit of double stds there to save them paying out more SC.
